Description

Die Erfindung betrifft ein Anschluss-Set gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a connection set according to the preamble of patent claim 1.

Ein Anschluss-Set der eingangs genannten Art ist aus dem Schutzrechtsdokument DE 298 21 805 U1 bekannt. Dieses Anschluss-Set besteht aus einem ersten Kanalabschnitt zur Führung eines Fluids in eine erste Richtung und aus einem zweiten, parallel zum ersten verlaufenden Kanalabschnitt zur Führung des gleichen Fluids, wobei beide Kanalabschnitte an ihren jeweiligen Enden Anschlussflansche und an ihrer Wandung jeweils einen Zusatzanschluss aufweisen. Ein solches Anschluss-Set dient zur Verbindung von Vor- und Rücklaufleitungen einer Heizungsanlage.A connection set of the type mentioned above is from the protective rights document DE 298 21 805 U1 famous. This connection set consists of a first channel section for conducting a fluid in a first direction and a second channel section running parallel to the first channel section for conducting the same fluid, with both channel sections having connection flanges at their respective ends and an additional connection on their walls. Such a connection set is used to connect the flow and return lines of a heating system.

Dokument DE 20 2013 105851 U1 offenbart den Oberbegriff des Anspruchs 1.document DE 20 2013 105851 U1 discloses the preamble of claim 1.

Der Erfindung liegt die Aufgabe zugrunde ein Anschluss-Set der eingangs genannten Art zu verbessern. Insbesondere soll ein Anschluss-Set mit verbesserten hydraulischen Funktionen geschaffen werden.The object of the invention is to improve a connection set of the type mentioned at the outset. In particular, a connection set with improved hydraulic functions is to be created.

Diese Aufgabe ist mit einem Anschluss-Set der eingangs genannten Art durch die im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale gelöst.This object is achieved with a connection set of the type mentioned by the features listed in the characterizing part of claim 1.

Nach der Erfindung ist also vorgesehen, dass an den Wandungen der beiden Kanalabschnitte zusätzlich zu den Anschlussflanschen und den Zusatzanschlüssen jeweils ein Anschluss zu einem zur Führung des Fluids vom einen zum anderen Kanalabschnitt ausgebildeten, dritten Kanalabschnitt vorgesehen ist.According to the invention, it is therefore provided that on the walls of the two channel sections, in addition to the connecting flanges and the additional connections, a connection to a third channel section designed to guide the fluid from one channel section to the other is provided.

Mit anderen Worten zeichnet sich das erfindungsgemäße Anschluss-Set somit dadurch aus, dass es einen Fluidaustausch zwischen dem ersten und dem zweiten Kanalabschnitt ermöglicht. Dies wird dadurch erreicht, dass die drei Kanalabschnitte fluidisch und in Form einer hydraulischen Weiche miteinander verbunden ausgebildet sind. Dank dieser Dreikammertechnik ist ein optimaler hydraulischer Ausgleich zwischen einem Primär- und einem Sekundärkreislauf gegeben.In other words, the connection set according to the invention is characterized in that it enables a fluid exchange between the first and the second channel section. This is achieved in that the three channel sections are connected to one another fluidically and in the form of a hydraulic switch. Thanks to this three-chamber technology, there is an optimal hydraulic balance between a primary and a secondary circuit.

Vorteilhafte Weiterbildungen des erfindungsgemäßen Anschluss-Sets ergeben sich aus den abhängigen Patentansprüchen.Advantageous developments of the connection set according to the invention result from the dependent patent claims.

Der Vollständigkeit halber wird noch auf das Patentdokument DE 10 2015 117 997 A1 verwiesen, aus dem aber ebensowenig ein dritter Kanalabschnitt bekannt ist, wie aus dem eingangs genannten Stand der Technik. Darüber hinaus ist bei der Lösung nach diesem Patentdokument eine hydraulische Weiche nur am Ende eines Gesamtstranges möglich, während bei der erfindungsgemäße Lösung grundsätzlich jeder Abschnitt (sofern mehrere vorgesehen sind, worauf unten noch genauer eingegangen wird) mit einer Weiche versehen sein können.For the sake of completeness, reference is made to the patent document DE 10 2015 117 997 A1 referenced, but from which a third channel section is just as little known as from the prior art mentioned at the outset. In addition, with the solution according to this patent document, a hydraulic switch is only possible at the end of an entire line, while with the solution according to the invention, each section (if several are provided, which will be discussed in more detail below) can be provided with a switch.

Das erfindungsgemäße Anschluss-Set einschließlich seiner vorteilhaften Weiterbildungen gemäß der abhängigen Patentansprüche wird nachfolgend anhand der zeichnerischen Darstellung eines bevorzugten Ausführungsbeispiels näher erläutert.The connection set according to the invention, including its advantageous developments according to the dependent patent claims, is explained in more detail below with reference to the graphic representation of a preferred exemplary embodiment.

Perspective and in cross-section the connection set according to Figure 1 and 2 .

Das in den Figuren dargestellte Anschluss-Set besteht zunächst in bekannter Weise aus einem ersten Kanalabschnitt 1 zur Führung eines Fluids und einem zweiten, parallel zum ersten verlaufenden Kanalabschnitt 2 zur Führung des gleichen Fluids, wobei beide Kanalabschnitte 1, 2 an ihren jeweiligen Enden Anschlussflansche 1.1, 2.1 und an ihrer Wandung jeweils einen Zusatzanschluss 1.2, 2.2 aufweisen.The connection set shown in the figures initially consists in a known manner of a first channel section 1 for guiding a fluid and a second channel section 2 running parallel to the first for guiding the same fluid, with both channel sections 1, 2 having connecting flanges 1.1 , 2.1 and each have an additional connection 1.2, 2.2 on their wall.

Wie weiterhin aus den Figuren ersichtlich, sind die Kanalabschnitte 1, 2, 3 erfindungsgemäß horizontal erstreckt verlaufend 15 ausgebildet.As can also be seen from the figures, the channel sections 1, 2, 3 are designed to extend horizontally according to the invention.

Die Anschlussflansche 1.1, 2.1, die auch nach dem Vorbild gemäß der DE 298 21 805 U1 als gemeinsamer Flansch ausgebildet sein können, dienen wahlweise zum Anschluss an einen Heizkreis eines Gebäudes oder aber auch, wenn mehrere Heizgeräte nebeneinander angeordnet werden sollen, wozu das Anschluss-Set besonders bevorzugt verwendet wird, zum Anschluss eines oder mehrerer weiterer Anschluss-Sets. Jedes einzelne Heizgerät ist dabei über die Zusatzanschlüsse 1.2, 2.2 mit dem Anschluss-Set verbunden.The connection flanges 1.1, 2.1, which are also based on the model according to the DE 298 21 805 U1 can be designed as a common flange, are used either for connection to a heating circuit of a building or, if several heaters are to be arranged next to each other, for which the connection set is particularly preferably used, for the connection of one or more further connection sets. Each individual heater is connected to the connection set via the additional connections 1.2, 2.2.

Wesentlich für das erfindungsgemäße, vorzugsweise gusstechnisch, insbesondere aus Grauguss, hergestellte Anschluss-Set ist nun, dass an den Wandungen der beiden Kanalabschnitte 1, 2 zusätzlich zu den Anschlussflanschen 1.1, 2.1 und den Zusatzanschlüssen 1.2, 2.2 jeweils ein Anschluss 3.1, 3.2 zu einem zur Führung des Fluids vom einen zum anderen Kanalabschnitt 1, 2 ausgebildeten, dritten Kanalabschnitt 3 vorgesehen ist.It is essential for the connection set according to the invention, preferably cast technically, in particular from gray cast iron, that on the walls of the two channel sections 1, 2 in addition to the connection flanges 1.1, 2.1 and the additional connections 1.2, 2.2 each have a connection 3.1, 3.2 to a for guiding the fluid from one channel section 1, 2 to the other, third channel section 3 is provided.

Erfindungsgemäß vorgesehen ist dabei, dass der dritte Kanalabschnitt 3 zwischen dem ersten und zweiten Kanalabschnitt 1, 2 angeordnet ist. Noch etwas genauer betrachtet, ist dabei vorgesehen, dass der dritte Kanalabschnitt 3 oberhalb des ersten Kanalabschnitts 1 und unterhalb des zweiten Kanalabschnitts 2 angeordnet ist.According to the invention, the third channel section 3 is arranged between the first and second channel sections 1 , 2 . Looking at it a little more closely, it is provided that the third duct section 3 is arranged above the first duct section 1 and below the second duct section 2 .

Weiterhin ist bevorzugt vorgesehen, dass die Anschlüsse 3.1, 3.2 an entgegengesetzten Enden des dritten Kanalabschnitts 3 angeordnet sind. Außerdem ist bevorzugt vorgesehen, dass der mit dem zweiten Kanalabschnitt 2 verbundene Anschluss 3.2 oberhalb des mit dem ersten Kanalabschnitt 1 verbundenen Anschlusses 3.1 angeordnet ist.Furthermore, it is preferably provided that the connections 3.1, 3.2 are arranged at opposite ends of the third channel section 3. In addition, it is preferably provided that the connection 3.2 connected to the second channel section 2 is arranged above the connection 3.1 connected to the first channel section 1.

Ferner ist besonders bevorzugt vorgesehen, dass der dritte Kanalabschnitt 3 wahlweise einen gemeinsamen Wandabschnitt 1.3 mit dem ersten Kanalabschnitt 1 und/oder einen gemeinsamen Wandabschnitt 2.3 mit dem zweiten Kanalabschnitt 2 aufweist, wobei in diesem Fall weiterhin besonders bevorzugt vorgesehen ist, dass der Anschluss 3.1, 3.2 als Durchgangsöffnung am gemeinsamen Wandabschnitt 1.3, 2.3 ausgebildet ist.Furthermore, it is particularly preferably provided that the third duct section 3 optionally has a common wall section 1.3 with the first duct section 1 and/or a common wall section 2.3 with the second duct section 2, in which case it is further particularly preferred that the connection 3.1, 3.2 is designed as a through-opening on the common wall section 1.3, 2.3.

Weiterhin ist bevorzugt vorgesehen, dass die Zusatzanschlüsse 1.2, 2.2 an zueinander benachbarten Enden der beiden Kanalabschnitte 1, 2 angeordnet sind.Furthermore, it is preferably provided that the additional connections 1.2, 2.2 are arranged on mutually adjacent ends of the two channel sections 1, 2.

Darüber hinaus ist vorgesehen, dass wahlweise der erste und/ oder zweite Kanalabschnitt 1, 2, vorzugsweise der zweite Kanalabschnitt 2, an seiner höchsten Stelle mit einem Entlüftungsventil 4 versehen ausgebildet ist.In addition, it is provided that optionally the first and/or second channel section 1, 2, preferably the second channel section 2, provided at its highest point with a vent valve 4 is formed.

Ferner ist vorgesehen, dass mindestens einer der beiden Zusatzanschlüsse 1.2, 2.2, vorzugsweise der zum ersten Kanalabschnitt 1 gehörende Zusatzanschluss 1.2, mit einer Pumpe 5, insbesondere Heizkreispumpe, versehen ausgebildet ist.It is also provided that at least one of the two additional connections 1.2, 2.2, preferably the additional connection 1.2 belonging to the first duct section 1, is provided with a pump 5, in particular a heating circuit pump.

Schließlich ist vorgesehen, dass mindestens einer der Kanalabschnitte 1, 2, 3, vorzugsweise der erste Kanalabschnitt 1, an seiner tiefsten Stelle mit einem Entleerungsanschluss 6 versehen ausgebildet ist.Finally, it is provided that at least one of the channel sections 1, 2, 3, preferably the first channel section 1, is provided with an emptying connection 6 at its deepest point.

Das erfindungsgemäße, als hydraulische Weiche arbeitende Anschluss-Set funktioniert wie folgt:
Ein Vorlaufanschluss eines Heizgerätes (typischer Weise ein wandhängender Gas- bzw. Ölheizkessel) ist hydraulisch mit dem Zusatzanschluss 2.2 verbunden, d. h. vom Heizgerät kommendes, vergleichsweise warmes Fluid (Heizkreiswasser) strömt über den Anschlussflansch 2.1 in einen Heizkreis, der wahlweise mit Heizkörpern und/oder Warmwasserspeichern versehen ist.The connection set according to the invention, which works as a hydraulic switch, works as follows:
A flow connection of a heater (typically a wall-mounted gas or oil boiler) is hydraulically connected to the additional connection 2.2, i.e. comparatively warm fluid (heating circuit water) coming from the heater flows via the connection flange 2.1 into a heating circuit, which can optionally be equipped with radiators and/or hot water storage is provided.

Sind mehrere Heizgeräte vorgesehen, können mehrere Anschluss-Sets nebeneinander angeordnet und über die Anschlussflansche 1.1, 2.1 miteinander verbunden sein bzw. werden. Ist nur ein Heizgerät vorgesehen, werden zwei der vier Anschlussflansche 1.1, 2.1 mit einem Deckelelement verschlossen, es sei denn die Anlage weist auch noch einen Warmwasserspeicher auf.If several heaters are provided, several connection sets can be arranged next to one another and connected to one another via the connection flanges 1.1, 2.1. If only one heater is provided, two of the four connection flanges 1.1, 2.1 are closed with a cover element, unless the system also has a hot water tank.

Vergleichsweise kaltes, vom Heizkreis zurückkommendes Fluid wird dem Anschluss-Set über den Anschlussflansch 1.1 zugeführt. Von dort strömt dieses Fluid über den Zusatzanschluss 1.2, der in seinem weiteren Verlauf mit einer Pumpe 5 versehen ist, zu einem Rücklaufanschluss des Heizgerätes.Comparatively cold fluid returning from the heating circuit is fed to the connection set via the connection flange 1.1. From there, this fluid flows via the additional connection 1.2, which is provided with a pump 5 in its further course, to a return connection of the heater.

Aus den obigen Erläuterungen ergibt sich, dass erfindungsgemäß vorgesehen ist, dass der erste, untere Kanalabschnitt 1 zur Führung eines vergleichsweise kalten und der zweite, obere Kanalabschnitt 2 zur Führung eines vergleichsweise warmen Fluids vorgesehen ist. Weiterhin ergibt sich aus den obigen Erläuterungen, dass der erste Kanalabschnitt 1 zur Führung des Fluids in eine erste Richtung und der zweite Kanalabschnitt 2 zur Führung des Fluids in eine zur ersten Richtung entgegengesetzten zweiten Richtung ausgebildet sein kann.It follows from the above explanations that it is provided according to the invention that the first, lower duct section 1 is provided for conducting a comparatively cold fluid and the second, upper duct section 2 is provided for conducting a comparatively warm fluid. Furthermore, it follows from the above explanations that the first channel section 1 can be designed to guide the fluid in a first direction and the second channel section 2 can be designed to guide the fluid in a second direction opposite to the first direction.

Sollte ein Leistungs- bzw. Druckausgleich zwischen dem Heizkreis und dem Heizgerät (also zwischen dem Primär- und dem Sekundärkreis) erforderlich sein, so kann dieser in optimaler Weise über den Kanalabschnitt 3 erfolgen, und zwar dadurch, dass das Fluid von einem der beiden Kanalabschnitte 1, 2 über den Anschluss 3.1, 3.2 in den dritten Kanalabschnitt 3 und von dort in den anderen Kanalabschnitt 2, 1 strömt. Bedingt durch die sich aus dem Aufbau des erfindungsgemäßen Anschluss-Sets ergebende Schichtung des Fluids im dritten Kanalabschnitt 3 erfolgt dieser Ausgleich mit einem sehr geringen Energieverlust.If a power or pressure equalization between the heating circuit and the heater (i.e. between the primary and the secondary circuit) should be necessary, this can be done in an optimal way via the channel section 3, in that the fluid from one of the two channel sections 1, 2 flows via the connection 3.1, 3.2 into the third channel section 3 and from there into the other channel section 2, 1. Due to the layering of the fluid in the third channel section 3 resulting from the structure of the connection set according to the invention, this equalization takes place with a very low loss of energy.

Der Vollständigkeit halber wird schließlich noch darauf hingewiesen, dass auch vorgesehen sein kann, dass der eine Anschlussflansch 2.1 den Vorlauf zu dem oder den Heizkreisen und der hierzu gegenüberliegende Anschlussflansch 1.1 den entsprechenden Rücklauf bildet.Finally, for the sake of completeness, it is pointed out that it can also be provided that one connecting flange 2.1 forms the flow to the heating circuit(s) and the opposite connecting flange 1.1 forms the corresponding return.
